WILLIAM S. MATHER, OF NEWARK, NEW JERSEY.

SPECIFICATION forming part of Letters Patent N o. 660,387, dated October 23,1900.

Application led April26, 1900. `Serial No. 14,390. (No model.)

To all whom, it nfl/ay concern:

Be it known that I, WILLIAM S. MATHER, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Crucible-Shakers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings and to letters of reference` marked thereon, which form a part of this specification.

This invention relates to that class of crucible-shakers represented by my prior application, filed January 20, 1900, Serial No. 2,100, the objects of the invention set forth herein being to provide a shaking-lever which may of itself prevent the crucible from slipping or walking about during the shaking operations, to secure a construction more rigid and positive in 'its action, to enable the workman to stand at a distance from the crucible, to enable the shaking-lever to be applied to the crucible with greater ease and quickness, and to secure other advantages and results, some of which may be referred to hereinafter in connection with the description of the working parts.

The invention consists in the improved crucible-shaker and in the arrangements and combinations of parts of the same, all substantially as will be hereinafter set forth, and finally embraced in the clauses of the claim.

Referring to the accompanying drawings, in which like letters of reference indicate corresponding parts in each of the several views, Figure l is a perspective view of my improved shaker as applied to a crucible. Fig. 2 is a vertical central section of the same; Fig. 3 is a detail section on line y, FigL-Z. Fig. 4 is a side elevation. Fig. 5 is a horizontal cross-section on line fr, Fig. 4; and Fig. 6 is a plan of the apparatus.

In said drawings, a indicates the crucible or melting-pot, which is to be filled while redhot with cold metal cut up into small pieces and must therefore be shaken or agitated while being filled to settle the contents and utilize the full capacity of the crucible. In eecting this shaking of the crucible a supportingsurface is provided for the crucible, which preferably consists of a flooring b, covered at the top with an iron plate b and having at the underside reinforcing strips or pieces b2. This supporting-surface is perforated, as at c, to form sockets for the lower ends of the legs d d of the shaking-lever, said perforations being countersunk or flaring at their mouths, as at c', to facilitate a quick and ready insertion of the shakin g-lever to its place. Said shaking-lever com prises two upright legs d d, normally disposed at diametrically-opposite sides of the crucible and only far enough away from said crucible to permit free independent movement. Said legs are preferably formed of heavy strap-metal, and at their bottoms are provided with rounded extremities d', adapted to be inserted in the sockets c, said extremities being either integral with the legs or separate pieces secured thereto, as shown. The said legs d of the shaking-lever carry between themselves a ring e, pivoted at its opposite sid es to the legs and adapted to tit around(v the tapering top of the crucible. Said ring is referably pivoted somewhat looselyand by means of oval or oblong perforatio'ns j in the legs d, which receive similarly-shaped but smaller trunnions e', projecting from the ring, the said shape of the parts preventing the ring from turning into edgewise position, so that itwill not readily pass down over the top of the crucible. The ring e is placed at such a height upon the legsA d as will permit the feet d' to be securely inserted in the sockets c when said ring e is seated upon the crucible.

When the upper ends of the legs d of the shaking-lever therefore are oscillated in a direction at right angles to the plane of the legs swinging upon their lower ends as pivots, the ring e, and with it the top of the crucible, is carried back and, forth and the crucible is given that rocking motion which best settles its contents.

To operate the shaking-lever, the tops of the legs d are preferably connected by a crosspiece f, and from this cross-piece extends an arm C, providing at its outer end a handle g for the operator to grasp, and thus said operator isenabled to stand at a considerable distance from the hot crucible while shaking it. For greater convenience this arm g niay be hinged or jointed, as at 7L, Fig. 5, thus permitting greater freedom of the handle end in manipulation; Preferably the operator stands behind a screen (not shown) interposed between himself and the Crucible to protect him from the heat, and the handle g facilitates the use of such a screen.

Lest the sockets c should become filled or clogged with pieces of metal dropped Vfrom the top ofthe Crucible during lling, I have `provided the legs (l with umbrellas or Ciently prolong said legs, so that the ring e4 can be raised above the Crucible and slipped to one side without withdrawing the feet d from their sockets, and in this Construction I may prefer to apply nuts 7c, a Cross-pin, or other equivalent stops to the bottoms of said feet, as indicated in Fig. 4.

Although the legs d of the shaking-lever prevent to a greater or less extent any creeping or slipping about of the Crucible while being lled,'l may .for greater security elnploy the pins t, projecting upward around the base of the Crucible.

Having thus described the invention, what I Claim as new isl-. A Crucible-shaker, comprising a baseplate, a shaking-lever having upright legs at opposite sides of the Crucible, said legs being fulcrumed at their lower ends on said baseplate and being provided between said legs with means for grasping the Crucible, substantially as set forth. V 2. A Crucible-shaker, comprising a baseplate, a shaking-levell having opposite legs fulcrumed upon said base-plate and adapted to swing in parallel planes tangent to the Crucible, and means upon said legs forgrasping the Crucible, substantially as set forth.

3. A Crucible-shaker, comprising a baseplate, a shaking-lever having legs at opposite sides of the Crucible, and a ring connecting said legs for encircling the Crucible, and said legs being fulcrumed at a distance from said ring, substantially as set forth.

4. A Crucible-shaker, com prisingasupporting-surface having sockets, and a shakinglever having a normally-horizontal ring for encircling the Crucible, and upright legs pivoted to said ring at opposite sides and adapted to be inserted at their ends into the sockets of the supporting-surface, substantially as set forth.

5. A Crucible-shaker, Comprising a socketed supporting-surface, and a shaking-lever having opposite legs adapted to be seated at their ends in said sockets, and means carried by said legs for grasping the Crucible, substantially as set fort-h.

6. A Crucible-shaker, Comprising a baseplate and means thereon for preventing the Crucible from slipping, a ring or band for encircling the Crucible, upright legs Connected to opposite points of said ring, and being pivoted to swing in planes tangent to the Crucible, and means for connecting said legs and operating them, substantially as set forth.

7. A Crucible-shaker, comprising a baseplate having sockets therein, a shaking-lever comprising opposite legs seated in said sockets, a Cross-piece and a handle, and means Carried by said legs for gras ping the Crucible, substantially as set forth.

8. A Crucible-shaker, comprising a baseplate having conical sockets and having pins for preventing lateral movement of the Cru- Cible, a shaking-lever having legs seated in said sockets, stops at the ends of said legs preventing their complete Withdrawal from the sockets, and means upon said legs for grasping the Crucible, substantially as set forth'.

9. A Crucible-shaker, Comprising a baseplate for supporting the Crucible, a ring adapted to encircle the Crucible, and a shaking-lever having legs at opposite sides of said ring and pivoted thereto by oval pins working loosely in similarly-shaped sockets, whereby the said ring normally assumes a given angular relation to said legs, substantially as set forth.

l0. In a Crucible-shaker, the combination of a socketed base-plate, a shaking-lever having means for grasping the Crucible and legs adapted to loosely enter at their ends the sockets in said base-plate and a shield or guard protecting the mouths of said sockets, substantially as set forth.

1l. 'In a Crucible-shaker, the combination of a supporting-surface for the Crucible, upright legs at the sides of the Crucible, said legs Carrying between themselves means for grasping the Crucible and being pivoted at a point away from said grasping means, and a jointed handle Connected to said legs for oscillating them, substantially as set forth.

12. In a Crucible-shaker, the Combination with a socketed base-plate, of a shaking-lever having legs fitting at their ends into said sockets, stops preventing the com plete withdrawal of said legs, means Carried by said legs for grasping the Crucible, and means for Connecting and pivotally oscillating said legs, substantially as set forth.

In testimony that I Claim the foregoing I have hereunto set my hand this 14th day of April, 1900.

WILLIAM S. MATI-IER.
